""but really deep down we all know we have to alter our eating habits don't we,""
Its interesting that that is what happened to the girl in the story after the surgery. -- she changed her eating habits.
Only with massive side effects.
I wonder if someone had sat her down and explained that the only benefit would be that she would be forced to change her eating habits would she have thought differently about the operation.
I doubt that the surgeon took the time to do that.
